I got to work a little early this morning and decided to upgrade to the new VirtualBox 3.0, which I use to run Ubuntu 9.04 as a guest on my 64-bit Windows Vista host machine.
The upgrade was simple as always and I experienced no issues … until I tried to boot up my Ubuntu VM. It appeared to hang during boot up, and finally ended in a kernel panic. Every time.
There’s an easy fix, however, which I found here after a quick Google search. The solution is to change the VM settings for the network adapter from “PCnet-FAST III” to “Intel PRO/1000 MT Desktop”.
